FAQs

• Is a tankless hot water heater unit the same as a continuous flow hot water unit >
  Yes, they are the same type of system. A tankless or continuous flow hot water unit heats water on demand, rather than storing it in a tank. This means you’ll never run out of hot water, and energy is only used when you turn on the tap - making it an efficient and space-saving option for many homes.
• How does an Efinity Electric Continuous Flow Hot Water system work >
  The Rinnai Efinity is a fully electric, continuous flow hot water system that heats water instantly as it flows through the unit—without the need for a storage tank. It operates using 3-phase power and is available in high-capacity models (14kW, 19kW, and 29kW), making it suitable for homes with high hot water demand. When a hot water tap is opened, the system automatically activates and begins heating water to the set temperature.
• What size Efinity Electric Continuous Hot Water unit should I choose for my house? >

  There are many factors to consider when sizing a hot water system for your home. It’s always best to consult with a Rinnai specialist / registered technican to ensure you make the right decision.

• Can the Efinity Electric Continuous Flow Hot Water system be installed inside or outside >
  The Efinity Electric Continuous Flow Hot Water unit is designed for ‘Indoor’ installation only.
• What power supply do I need for an Efinity Electric Continuous Flow Hot Water system >
  This appliance must be connected to an independent, fused AC 380–415V, 3-phase, 50Hz power supply, with an isolating switch installed at the switchboard. The isolating switch must completely disconnect all active supply conductors from the circuit, and provisions for disconnection must be incorporated into the fixed wiring in accordance with the Wiring Rules.
• How energy efficient is the Efinity Electric Continuous Flow Hot Water units? >

  The Rinnai Efinity Electric Continuous Flow Hot Water units are generally more energy efficient than traditional electric storage hot water systems. This is because Efinity units only heat water on demand, meaning they activate and use power only when hot water is needed.

  In contrast, electric storage systems continuously use energy to heat and maintain the temperature of water stored in a tank, even when it's not being used. By eliminating standby heat loss and unnecessary heating cycles, Efinity systems can help reduce overall energy consumption and lower electricity costs.
